IMPROVEMENT lN FACE-PLATES AND STRIKES FOR LQCKS.

Specification forming part of Iaetters Patent No. 126,846, dated May 14,1872.

To all whom it may concern:

Be it' known that I, JOHN M. SPRING, of

New Britain, in the county of Hartford and l State of Connecticut, haveinvented an Imshape adapted to the edge of the door and to theface-plate. These faceplates and strikes are very diicult to tile up andfinish, because there are angles and recesses that can only be finishedup by scraping; hence these parts are diiiicult to finish handsomely andare costly.

lMy invention consists in a face-plate or strikeplate made with a flangethat is separate from the plate itself, and provided with projections isan edge View; and Fig. 4 is a section of the strike.

The plate a is ida-t and of the proper shape.

The flange b and its plate c are also of the size and shape adapted tothe peculiar lock or strike. In I5 same forms the face or front plate,while in Fig. 2 the openings fg are in the plate a, because the same isthe strike. The ange'b and its plate c are easily finished, because thesurfaces that are visible are at each side of the exterior angle 2;therefore such surfaces can be easily filed and nished, and the surfaceof the plate a is fiat, or nearly so; and hence can be dressed oft' orfinished by a file or otherwise. The parts .a and b are secured togetherby-rivets t, made preferably of pins projecting from the edge of theflange b.

It will now be understood that by this construction the internal angle 3is finished with facility, because the surfaces are filed up before theparts are united. Heretofore the finishing up of this internal angle 3has been difficult and costly, as before set forth.

I claim as my inventiony The face-plate or strike made of the plate aand iiange b, in two parts, united together as and for the purposes setforth.

Signed by me this 12th day of March, A.
